Welcome to the forum, If you've used AMOS in the past and can remember any of it then you will soon be up and running as it almost the same once you get around how the little clever bits work.
So if you have brought DBPro then run all the Demos the start breaking them by changing something.
some things you may want to check how to do.
1. print to screen (so simple but the number of question ask on this is very high)
2. placing an object on screen and the camera.
3. loading and saving data.
Plus there a whole load of tutorials to be found in this thread,

So have fun coding and who knows soon you could answering the question on here.
